You can swap partners with any and every guy in attendance, just so that you would be able to taste everything that's on the menu. That is why they would rather participate in orgies, parties wherein the main activity is having sex with one another.
Sometimes, just one serving of cum is not enough for horny gay men. What matters is that they would be able to see, smell, touch, and even taste cum, and would offer their own load to their partner in return. Some guys have a thing for feet or armpits even though they still have a set of those body parts on their own person. You can't really blame him, because that is what he's attracted to. The main point is that even if a gay guy could already produce his own semen just by masturbating by himself, he would still seek the taste of someone else's whenever he gets the chance to do so. Cum, semen, jizz, spunk, seed, spurt, load, skeet, whatever you want to call it.
Every gay man's dream is to be able to taste the nectar that comes from another man's penis.
